Humans have caused 1.5 °C of long-term global warming according to new estimates

Looking into the numbers a couple if months ago I was surprised how little it costs to stop climate change.

On the order of 100-200 trillion USD. Which is roughly 100-200% of global yearly GDP. Or 2-5% of yearly GDP until 2050. This could well be provided by printing money at all the federal reserve banks.

This investment will likely bring in a positive return on investment because it reduces the negative climate impacts.

Without such investments the downstream costs in climate change adaptation will be very expensive

If you're referring to he economist one, I've read it too, and I think it would be much cheaper.

But anyway, I don't believe half the numbers out there.

To cut emissions, we need to kill materialism, consumption economy and most importantly tell people that they should choose between what's good for them (eating a burger to make them happy) or the planet (not bringing the equivalent pollution of driving an SUV 50 miles+ by eating something much less polluting than beef).

Governments will keep chasing the kind of changes that can only make more money, not less.

> To cut emissions, we need to kill materialism, consumption economy

That’s a moral statement not a factual one. To cut emissions, we need to do exactly that. Pricing in externalities (yes it means less beef but that’s not the same thing as an end to the world as we know it) and investing in cleaner means of production is enough. Most of the people pushing for large societal changes are doing it because it was their goal from the start and they are using climate change as a mean to an end.

Lucky the Earth is infinite and so perpetual growth will work. /s
